Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, CHARLES W. DEMOOY, a citizen of the United States,residing at #1833 East th St., in the city of Cleveland and State ofOhio, have invented a new and useful Improvement in High-FrequencyMachines, of which the following is a specification, the prlnclple ofthe lnvention being herein explained and the best mode in which I havecontemplated applying that principle, so as to distinguish it from otherinventions.

My invention pertains to high frequency machines and more particularlyto an electrical apparatus of this class adapted for therapeuticalpurposes which comprehends an electrical stimulus or localized massageand the production of ozone.

()ne object the invention is to provide a simple, compact and economicalapparatus with a novel arrangement and connection.

of certain parts whereby advantageous results are secured with a boxconvenient of access and easy to carry. I especially recommend therelative arrangement of my terminal conducting points and in con unctionthere-with the interposed location of a suitable dielectric. Such isdesigned to effect a greater efiiciency with a given size or area ofterminals and to require less space.

A further object is to establish ease of access for inspecting thecontact points for cleanin or repair.

Another ob ect is the provision of a umtary structure both forregulating the action between the contact points, and for covering themto simultaneously protect them against damage or short circuiting, andobviate all risk of shock to the operator.

A final object has been to so contrive the connections that when a shortcircuit or break in the wiring occurs, not only will the machineimmediately cease to operate but the current will also stop to preventburning of the contact points.

The essentials heretofore long since employed are a source of electricalcurrent, an electromagnet (resonator), a pair of contacts, an inductioncoil, a set of terminals and a condenser. These agencies togetherfunction to produce electrical discharges which may be utilized byconcentrating their delivery from a dielectric electrode or byoccasioning a gaseous reaction due to a stat c discharge to produceozone. The intenslfication of the violet rays in either case is readilycontrolled. When current passes through the outer heavier wires of theinduction around. A magnetic field is produced in which the multitude ofthin inner wires rest. As the current is broken in the outside wiring anelectromotive force is created occasioning a rush of current through thefine inside wiring with a tremendously high electromotive force. Theresonator thereafter intermittently closes the circuit and the operationand resultin discharge is repeated. I am well aware t at a series ofconductmg points over a given terminal area have been before used todistribute the high fre quency current, also that dielectric surfaces,usually glass, have been interposed to compensate for any tendency toproduce a discharge which will not be uniformly distributed. During theenergizing, the charges of opposite polarity on the conducting pointswhich are opposed to each other, create between the ground and theterminal of the induction coil the stresses incident to theelectrostatic field. My idea consists in placing the two sets of sparkpoints in substantially vertical and parallel planes whereby thedielectric or U tube as is shown in Fig. II, may be supported betweentwo instead of alongside only one set. Moreover, this arrangement oflersthe advantage of inducin a natural air current due to the generated heatand so simply but effectively ozonizes the vicinity. When the machine isutilized for discharging concentrated violet rays from a dielectricelectrode, I prefer to line the hollow interior of the same with somemetallic substance, having discovered one of such manufacture to be noless efficient than those having a near vacuum, and more durable becauseequally useful even when punctured or broken.

With the foregoing and other objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown the preferred coil lines offorce are created thereembodiment of the invention, but it is to beunderstood that changes, variations and modifications can be resorted towhich come within the scope of the claims hereunto appended.

Adverting to the drawings Figure I is a plan of a machine embodying myinvention with its cover lifted.

Fig. IIis a zig-zag section on line II II of Fig. I looking in thedirection indicated by the arrows.

Fig. III is a vertical section taken on line III III of Fig. II.

Fig. IV is an enlarged side view of one detail with a part broken away.

Fig. V is a diagram of all the electrically connected parts.

The apparatus disclosed by the drawing is contained in a suitablereceptacle and while the compactness of its interior arrangementconstitutes one of the features of my invention the majority of theparts may be very briefly referred to because the individual functionthereof has long been known and used. The receptacle includes a hollowlower compartment 1 and a hollow cover 2 of nearly equal size which ishinged thereto, which carries, above, a suitable handle 3 and which isprovided in its interior with a number of supports adapted to hold inplace the various paraphernalia usually required in the operation of ahigh frequency or ozonizing machine when devoted to therapeuticalpurposes. -The compartment 1 carr1es near its top a frame 4 throughwhich certain parts extend bywhich certain other parts are suitablysupported. A main either A C or D, C electrical current cable, includingwires 5 and 6 which are connected with the source of current, enters thecompartment 1 through an opening provided in the member 4 at one endthereof.

Near its other end the member 4 is provided with an opening 7 ofconsiderable size beneath which a conducting plate 8 is supported in anupright position. This plate carries a pluralit of terminal points 9which areprefera 1y about equally spaced over the area thereof. Opposedto plate 8 on the other side of the opening 7 so as to be spaced 2.given distance therefrom is a similar conducting plate 10 which is alsoprovided with a corresponding series of terminal points 11. Thiarrangement may be seen upon inspection of Figs. II and V. Theconducting plate 8 may be considered as the ground in its relation tothe other parts to be included in the same electric circuit. A block 12carrying a retaining pin 13, as shown in Fig. III, is fitted to andadapted for insertion in the opening 7 This block 12 carries in anyapproved manner a depending dielectric U tu'be customarily composed ofglass and open at one end. The disposition of the U tube 14 when theblock 12 is in place is substantially midwa between the terminal points9 and 11 S110 that the ozone created by the high frequency dischargesthereacross may be, to a certain extent, held in suspense by the oilolution contained in the bottom of the tube. According to my inventionthe compartment '11 is provided, underneath the U tube 14, with a seriesof openings 15 through which a natural current of air is caused to riseowing to the generation of heat thereabove. Such a current serves tocirculate and distribute ozone for direct inhalation when desired. Thegeneral disposition of the contact points 9 and 11 with'relation to theupright tube 14 effects a considerable saving in space and increases thefacility of assemblage as well as efficiency in operation.

Between the openings for the insertion of the wires 5 and 6 and theopening 7, the member 4: is provided with another opening 16 throughwhich certain parts of the electromagnet 17 which is supportedtherebeneath, extend. Included among such parts is a resilientmember--18 carrying a contact point 19 which is adapted to vibrate inthe usual way when the electromagnet becomes energized as willhereinafter become evident. Placed in one corner of the receptacle I isa condenser 20 of any approved type as appears in Fig. II. The requisiteinduction coil 21 is also represented in this figure, its line beingdotted because in front of the plane on which the section is taken.

The manner in which I connect the condenser 20 with the rest of thesystem or circuit constitutes another feature of my invention, theexplanation of which will, however, more logically occur farther on inthis description.

Mounted to one side of the contact point 19 which is disposed upon themember 4 is a bracket 22 to which one end of a frame 22 i hinged. Thisframe extends over contact 19 and carries a pair of flanges 23 dependingon each side thereof so as to inclose the contact 19 when the frame 22is swung downwardly. In this latter position another contact 25 carried:by another resilient'member 24 is adapted to come into superposition inopposition to the contact 19. The disposition of the contacts 19 and 25with regard to each other may be effected by means of a thumb screw 26which also simultaneously secures the frame 22 to the member 4 as may bereadily perceived upon inspection of either Figs. II or IV. Loosening ofthe screw 26 will permit the frame 22 to be sw'ung upwardly, thusseparating the points 19 and 25 and readily permitting the inspectionthereof. When on the other hand, the frame 22 is secured in place itsflanges 23 effectually hinder access of an operators fingers to thecontacts whenever the apparatus is energized.

' Directing attention now to the diagram matic view seen in Fig. V, inorder to comprehend the manner of effecting electrical connectionbetween the essential parts, it will be noticed that after the currenthas passed through the wire 6, through the electro magnet 17, member 18,contacts 19 and 25 and member 24, it is enabled to continue along a wire27 leading to an ozone switch 28; thence along the wire 29 to aninduction coil 21, pass along a wire 30 and out by equalizing thepotential at the points 19 and 25, thereby preventing the burning of thelatter. For example, should a short ClrClllt or break in the wiringoccur anywhere the induction coil would be cut out of the circuit thusgreatly increasing the potential on one side which if allowed to runback through the primary 17 would occasion a damaging heat generatingflash at the contact points. As wired by me, the condenser 20 functionsin the event of either happening just mentioned and acts as ashunt tosave the points and stop the machine. The operation of a machine of thecharacter described is ordinarily such that when the current is broken,owing to pulsations of the electromagnet, the high potential set up issuflicient to run through the wire 33 to the ground and from there jumpacross and be led back by the wire 34.

The flow of the current as thu far considered under varying conditionshas referred to the ozonizing unit of my machine. When it is desired toeffect an application to the body of violet-rays the switch 28 is thrownout and current carried instead from the wire 27 to the wire 35 thencethrough the other or high frequency switch 36 alon the wire 37 throughanother induction coil 38 and back to the wire 5 by means of theconductor 39.v It is primarily when the machine is so utilized foreffecting high frequency discharges from a manipulated dielectricelectrode that the condenser 20 is intended to function as alreadydescribed because a fracture is most likely to occur and occasion ashort circuit owing to a repeated twisting and bending of the cablewhich carries the wires 37 and 39 as illustrated in Fig. I.
